Income Tax Disclosure [Abstract] |
INCOME TAXES | 15. INCOME TAXES Prior to consummation of the Corporate Reorganization, SMLP was treated as a partnership for federal and state income tax purposes, in which the Partnership’s taxable income or loss was passed through to its unitholders. SMLP was subject to Texas margin tax. Therefore, with the exception of Texas, SMLP did not directly pay federal and state income taxes and no entity-level income tax provisions was recorded other than for the effects of the Texas margin tax. Summit Midstream Corporation’s effective income tax rate for the nine months ended September 30, 2025 was different from the U.S. federal statutory income tax rate of 21% primarily due to the net income allocated to the noncontrolling interest, tax benefits related to stock-based compensation and nondeductible executive compensation. The effective tax rate for the nine months ended September 30, 2024 was different from the U.S. federal statutory income tax rate of 21% primarily due to SMLP’s pre-Corporate Reorganization income not being subject to U.S. federal or state income tax, other than the Texas margin tax. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized, and when necessary, valuation allowances are provided. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. SMC assesses the realizability of its deferred tax assets quarterly and considers carryback availability, the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. No valuation allowance has been recognized as of September 30, 2025. On July 4, 2025, President Trump signed into law the One Big Beautiful Bill Act (“OBBBA”). The OBBBA preserves the 21% U.S. Federal statutory tax rate and makes a favorable change to the business interest expense limitation. Further, the OBBBA also makes key elements of the Tax Cuts and Jobs Act permanent, including 100% bonus depreciation, domestic research cost expensing, and various expiring international provisions (with some modifications). Pursuant to ASC 740, changes in tax rates and tax law are required to be recognized in the period in which the legislation is enacted. The passage of the OBBBA did not have a material impact to tax expense for the nine months ended September 30, 2025.
